Please stop freeloading on our electricity, food, sanitation, roads, police/fire/education, the US military, and thousands of other services, renounce your citizenship, and leave at your earliest convenience. The US is pretty frothy about undocumented immigrants these days, so I would advise you not to dither.

I don't live in the us so I'm not using your electricity. I'd argue the pettiness of your argument if it were at least applicable.

Then s/US/<your country>. It applies equally.

You know not voting isn't a choice for some people, right?

Oh you mean like, felon/child/etc. suffrage? I'm fully in favor of extending the franchise to every living American; I think it's a fundamental right and morally outrageous that we ever deny it.

But I don't think that that means representative democracy in the US is a sham, equivalent to the level of representation I have at Facebook (again, zero). That would be a strawman.
